john 6:16 And when even was now come, his disciples went down unto the sea, - Free Bible Online

      16, 17. when even was come--(See on Mr 6:35).
      entered into a ship--"constrained" to do so by their Master (Mt 14:22; Mr 6:45), in order to put an end to the misdirected excitement in His favor (Joh 6:15), into which the disciples themselves may have been somewhat drawn. The word "constrained" implies reluctance on their part, perhaps from unwillingness to part with their Master and embark at night, leaving Him alone on the mountain.
      went--rather, "were proceeding."
      toward Capernaum--Mark says (Mr 6:45), "unto Bethsaida," meaning "Bethsaida of Galilee" (Joh 12:21), on the west side of the lake. The place they left was of the same name (see on Mr 6:32).
      Jesus was not come to them--They probably lingered in hopes of His still joining them, and so let the darkness come on.
